document.write( "Question 1013656: A diagonal of a rhombus is 20cm long.if its one side is 26cm long,find the length of its other diagonal. \n" ); document.write( "
Algebra.Com's Answer #629913 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Since diagonals of a rhombus meet at right angles, you have 4 right triangles with the sides being the hypotenuses...the legs are 10 and x with the hypotenuse being 26...draw it and see... \n" ); document.write( "Anyway, the missing half-diagonal is found by \n" ); document.write( "10^2 + x^2 = 26^2 \n" ); document.write( "x = 24 \n" ); document.write( "so that the whole missing diagonal is 48 cm. \n" ); document.write( " |
